The type of network a container uses, whether it is a bridge, an overlay, a macvlan network, or a custom network plugin, is transparent from within the container.From the container’s point of view, it has a network interface with an IP address, a gateway, a routing table, DNS services, and other networking details (assuming the ...

docker network inspect: Returns information about one or more networks. By default, this command renders all results in a JSON object.

When you connect an existing container to a different network using docker network connect, you can use the --ip or --ip6 flags on that command to specify the container’s IP address on the additional network. In the same way, a container’s hostname defaults to be the container’s ID in Docker. You can override the hostname using --hostname.

Jan 13, 2018 · Docker uses network bridge for all traffic, and by default containers will be using bridge named docker0. However if you are using docker-compose , which by default creates own bridge for each configuration or you have other ways to configure docker networking the bridge you would like to capture would be different.

This container can access the internet if it is not assigned to the network I created, but not when connected to the network I created. Since my networking knowledge is limited I am struggling to find where to start in debugging this issue. A solution to this particular problem would be great, but a way to debug this issue would be even better.

Docker container process debugging Docker is just a fancy way to run a process, not a virtual machine. Therefore, debugging a process "in a container" is also possible "on the host" by simply examining the running container process as a user with the appropriate permissions to inspect those processes on the host (e.g. root).

Use IPv6. If you need IPv6 support for Docker containers, you need to enable the option on the Docker daemon and reload its configuration, before creating any IPv6 networks or assigning containers IPv6 addresses. When you create your network, you can specify the --ipv6 flag to enable IPv6. You can’t selectively disable IPv6 support on the default bridge network.
